Roux-en-Y gastric bypass (RYGB) has emerged as the most effective treatment in reversing insulin resistance in patients with type 2 diabetes mellitus (T2DM). A number of models and statistical tools have been proposed to predict patients likely to experience diabetes remission post-RYGB. The purpose of our study was to evaluate the preoperative accuracy of DiaRem score in predicting T2DM remission at 1 year of follow-up in a retrospective analysis of diabetic morbidly obese patients who underwent RYGB. One hundred and forty-three patients underwent RYGB between January 2018 and December 2018. We conducted a retrospective analysis in 55 patients (38.46%) with T2DM with 1 year of follow-up. DiaRem score was calculated, and patients were stratified in five groups. At a 1-year follow-up, we found a higher proportion of patients with T2DM remission in the lower score group compared to a lower proportion of patients with remission in the higher score group. We derived a DiaRem cut-off score of 6.5 that had high sensitivity and specificity to predict T2DM remission preoperatively. We found a significant decrease in BMI and HbA1C values post-operatively at 1 year following RYGB. DiaRem score is an easy to determine score based on basic clinical parameters that could identify patients with T2DM who would achieve maximal benefit in terms of remission after bariatric surgery. The development of a suitable scoring tool would be clinically useful as it would enable clinicians to better triage patients for RYGB.

Background: It has been suggested that patients with a Body Mass Index (BMI) of > 60 kg/m2 should be offered expedited Bariatric Surgery (BS) during the Coronavirus Disease-2019 (COVID-19) pandemic. The main objective of this study was to assess the safety of this approach. Methods: We conducted a global study of patients who underwent BS between 1/05/2020 and 31/10/2020. Patients were divided into three groups according to their preoperative BMI - Group I (BMI60 kg/m2). The effect of preoperative BMI on 30-day morbidity and mortality, procedure choice, COVID-19 specific safety protocols, and comorbidities was assessed. Results: This study included 7084 patients (5197;73.4 % females). The mean preoperative weight and BMI were 119.49 ± 24.4 Kgs and 43.03 ± 6.9 Kg/m2, respectively. Group I included 6024 (85 %) patients, whereas Groups II and III included 905 (13 %) and 155 (2 %) patients, respectively. The 30-day mortality rate was higher in Group III (p = 0.001). The complication rate and COVID-19 infection were not different. Comorbidities were significantly more likely in Group III (p = 70 kg/m2 had a 30-day mortality of 7.7 % (2/26). None of these patients underwent a Roux-en-Y Gastric Bypass. Conclusion: The 30-day mortality rate was significantly higher in patients with BMI > 60 kg/m2. There was, however, no significant difference in complications rates in different BMI groups, probably due to differences in procedure selection.

Bariatric and metabolic surgery are being performed in India for 2 decades. Aim of this paper is to evaluate the changing clinical trends over the last 5 years and to present the other aspects helmed by Obesity and Metabolic Surgery Society of India (OSSI) to aid the growth of research, education, data management and registry, quality control, insurance-related issues and policy change. OSSI conducts an annual survey to collect data pertaining to numbers of surgical procedures. With the approval of the executive committee, data collected from 2014 to 2018 were retrieved and analysed. 20,242 surgical procedures were performed in 2018 which is an 86.7% increase from 2014. Laparoscopic sleeve gastrectomy continued to remain the most popular procedure, it’s percent share saw a steady decline from 68 to 48%. One anastomosis gastric bypass showed an unprecedented growth from 14 to 34%. Numbers of laparoscopic Roux en y gastric bypass remained constant at 15–16%. OSSI has also initiated a COE program along with training fellowships and focus on registry and inclusion in insurance coverage. National trends over the past 5 years in bariatric surgery have shown emergence of newer procedures like OAGB, although LSG continues to be the most popular procedure performed These trends give an insight on how the field is evolving and the implications for any distinctive requirements unique to this region These will lay out important directives for not only ensuring good treatment outcomes but also increasing awareness about the disease on the whole.

Primary lumbar hernia is a rarely encountered hernia. Surgical correction is the standard treatment for lumbar hernia, and either an open or laparoscopic procedure can be performed with equivalent success. However, open repairs are most commonly performed. Here, we present a case of a primary lumbar hernia that was successfully treated laparoscopically and discuss surgical modalities of treatment reported in the literature. There are two laparoscopic approaches: transabdominal and extraperitoneal. The main advantage of the laparoscopic approach is that it helps the surgeon to precisely locate and evaluate the characteristics of the defect. It also has a lower morbidity rate, shorter length of hospital stay, less postoperative pain, and an earlier return to daily routine activities than the open approach. In the present study, a patient with a superior lumbar hernia was treated laparoscopically by the transabdominal approach. Laparoscopic repair in such cases is feasible and achieves a good result when done by an experienced laparoscopic hernia surgeon.

Iatrogenic enterotomy (IE) during laparoscopic ventral/incisional hernia repair (LIVHR) is reported to be associated with poorer surgical outcomes. We report our experience with diagnosis, management and complications in patients who had IE during LIVHR at our tertiary referral institute between 1994 and 2011. We retrospectively reviewed prospectively collected data of 2,346 patients who underwent LIVHR from 1994 to 2011. We identified 33 patients who had IE during LIVHR. All surgical procedures were performed by five consultants and fellows under supervision who followed a standardized operative protocol. Patients were followed up for 6 months to evaluate morbidity, mortality, additional surgical procedures, unplanned readmissions and hospital stay. Mortality occurred in 2 patients (6 %). Complications occurred in 16 patients (48.5 %). Median hospital stay was 3 days (2–36). Unplanned readmission was required in 6 patients (18 %). In 18 patients, (55 %) additional surgical procedures were required within 6 months of LIVHR. In 5 patients, the enterotomy was recognized postoperatively. These patients had worst outcomes [mortality 40 %, additional surgical procedures were required in all patients (100 %) and median hospital stay was 12 days (range 7–36)]. Iatrogenic enterotomy is a serious complication during LIVHR. IE is associated with mortality, morbidity, additional surgical procedures, unplanned readmissions and prolonged hospital stay. In patients where IE was recognized postoperatively, the prognosis was worst.

Laparoscopic ventral hernia repair (LVHR) with intra-peritoneal mesh placement is standard surgical treatment of abdominal wall hernias. During laparoscopic re-intervention, we examined adhesions that develop after previous intra-peritoneal mesh placement and ascertained morbidity and risk of adverse events. This is a retrospective, case-matched comparison of three patient groups—previous intra-peritoneal mesh (Group A), previous abdominal surgery (Group B) and no previous abdominal surgery (Group C). Matching was based on surgical procedure performed during laparoscopic re-intervention in Group A. Adhesions were described as grade, extent of previous mesh/scar involvement, involvement of abdominal quadrants and dissection technique required for adhesiolysis, each component being assigned value from 0 to 4. Total adhesion score (TAS) was generated as summative score for each patient (0 to 16). Access/adhesiolysis-related injuries, additional port requirement, deviations from planned surgery, operative time and length of hospital stay was noted. Relative risk of adverse events, i.e., inadvertent injuries and deviations from planned surgery, was calculated for Group A. Adhesion characteristics were most severe (highest TAS) in Group A. Access injuries occurred in 5, 4, 1.3% in Groups A, B, C, respectively. Adhesiolysis-related injury rate was 9%, 2.6% in Groups A, B, respectively. Relative risk of adverse events was 4 for Group A (compared to Groups B and C combined). Additional port requirement was highest for Group A. Mean operative time and length of hospital stay was significantly longer in Group A for LVHR. Intra-peritoneal mesh placement is associated with adhesion formation that may increase risk during subsequent laparoscopic surgery.

Laparoscopic Roux-en-Y gastric bypass (LRYGB) is one of the most effective bariatric procedures. Internal hernia (IH) is the commonest long-term complication seen after LRYGB. We analyzed the impact of closure of mesenteric defect at primary surgery on the incidence of IH. We also studied the effectiveness of pre-operative abdominal contrast-enhanced computerized tomography (CECT) in diagnosing IH. This is a retrospective cohort study in which we analyzed prospectively the collected data of all patients who underwent LRYGB from 2005 to 2014. All patients post-LRYGB presenting with unexplained abdominal pain with a suspicion of IH were subjected to a CECT abdomen, in which we looked specifically for “whirlpool” sign and “clustering of bowel loops.” All patients underwent diagnostic laparoscopy. We compared the incidence of IH in those who did not undergo mesenteric defect closure (2005–2008, i.e., group A) with those who had the mesenteric defects closed during primary surgery (2009–2014, i.e., group B). We also calculated the sensitivity of abdominal CECT in diagnosing IH pre-operatively. Among patients who did not undergo closure of any mesenteric defect (group A 2005–2009), 21/600 (3.5 %) developed IH, while 17/976 (1.7 %) patients who underwent mesenteric defect closure (group B 2009–2014) developed IH (p = 0.027). Pre-operative CECT abdomen confirmed the diagnosis of IH in 47.5 % (19/40 patients). Closing of mesenteric defects after laparoscopic gastric bypass seems to be related to a lower incidence of internal hernia in the follow up. As the sensitivity of abdominal CECT is low, laparoscopic exploration is recommended based on clinical suspicion.

Suprapubic hernias are considered difficult to repair laparoscopically due to deficient posterior rectus sheath and proximity to important neurovascular structures and the urinary bladder. We retrospectively reviewed 72 patients (18 males, 54 females) who, between 1998 and 2008, had undergone laparoscopic repair for suprapubic hernial defects located less than 5 cm from the pubic arch. Five patients (6.9%) had recurrent hernias. A peritoneal flap was dissected distally to facilitate a mesh overlap of at least 5 cm from the hernial defect. The lower margin of the mesh was fixed under direct vision to Cooper’s ligaments bilaterally. The raised peritoneal flap was reattached to the anterior abdominal wall thereby partially extraperitonealizing the mesh. Mean diameter of the hernial defect was 5.2 cm (range = 3.1–7.3 cm) as measured intraperitoneally. Mean size of the mesh used was 328.8 cm2 (range = 225–506 cm2). Mean operating time was 116 min (range = 64–170 min). Overall complication rate was 27.8%. There were no conversions. No recurrences were observed at a mean follow-up of 4.8 years (range = 1.2–6.9 years) and a follow-up rate of 84.7% A mesh overlap of at least 5 cm and fixation of the lower margin of the mesh under direct vision to Cooper’s ligaments appears to confer increased strength and durability and contribute to low hernia recurrence rates in patients with suprapubic hernias.

The role of laparoscopy in the management of incarcerated (irreducible) ventral hernia remains to be elucidated. We present our experience of the laparoscopic repair of incarcerated primary ventral and incisional hernias over an 8-year period. A retrospective review of the records of 112 patients undergoing laparoscopic repair for incarcerated primary ventral and incisional hernias from January 1998 to February 2006 was performed. The patient demographics, perioperative data, and postoperative complications were assessed. The procedure was completed entirely laparoscopically in 103 patients (91.9%) with the placement of intraperitoneal mesh. A sutured tissue repair (without mesh) was performed in seven patients and hernia repair was abandoned after laparoscopy in two patients. Five patients required limited conversion by a targeted skin incision for the resection of nonviable bowel (three patients) and to complete adhesiolysis within multiloculated hernial sacs (two patients). The contents of the hernial sacs were incarcerated omentum (42 patients), small bowel (28 patients), large bowel (six patients), and omentum and small bowel (34 patients). Of these, seven patients presented with signs of acute small-bowel obstruction. The mean size of the largest defect through which incarceration occurred was 3.5 ± 1.6 cm (range 1.5–7.5 cm) and the mean size of the mesh used was 379 ± 210 cm2 (range 225–780 cm2). The mean operative time was 96 ± 40.8 min (range 50–170 min). Inadvertent enterotomy occurred in four patients during bowel reduction and adhesiolysis. In two patients, the enterotomy was repaired by total laparoscopy followed by mesh placement, and two patients required conversion to formal laparotomy due to long-segment tears and peritoneal contamination. The average postoperative hospital stay was 2.8 ± 1.5 days (range 1–6.5 days). Postoperative complications occurred in 20.5% patients. There was no mortality. Hernia recurred in three patients at a mean follow-up of 48 ± 28.3 months (range 1–84 months). Laparoscopic ventral abdominal wall hernia repair can be safely performed with a low complication rate, even in incarcerated hernias. Careful bowel reduction with adhesiolysis and mesh repair in an uncontaminated abdomen with a 5-cm mesh overlap remain key factors for a successful outcome.

During laparoscopic ventral/incisional hernia repair (LVIHR), conversion to conventional (open) technique is required when safe adhesiolysis is not possible, incarcerated bowel in hernial sac cannot be reduced or for repair of iatrogenic enterotomies. A formal laparotomy in these circumstances entails significant morbidity due to factors such as wound infection, prolonged immobility, and longer hospital stay. During a period between 1994 and 2007, 1,503 LVIHRs were performed at our centre following a standardized protocol by five consultants and fellows. Out of these, 6 patients had a formal laparotomy in the initial part of our experience and 26 patients had a limited conversion to facilitate completion of LVIHR. We have devised the term “limited conversion” for the procedure wherein bowel reduction/adhesiolysis/enterotomy repair was performed through a small targeted skin incision. This was followed by laparoscopic placement of intraperitoneal mesh. Conversion to an open procedure was required in 32 (2.1%) out of 1,503 LVIHR procedures. Twenty-six patients underwent a limited conversion and completion of the repair by laparoscopy. All but one of these patients had intraperitoneal placement of mesh by laparoscopic route. The wound complication rate was 3.8% (one patient), the mean hospital stay was 2.1 days, and mean operative time was 124 min. Limited conversion offers a safe alternative to a formal laparotomy in patients with bowel incarcerated in hernial sacs or in patients requiring extensive bowel adhesiolysis. Patient morbidity is reduced due to the targeted skin incision whilst retaining several advantages of a minimal access approach viz. laparoscopic evaluation of the entire abdominal wall and placement of a large intraperitoneal prosthesis.

Background To evaluate the feasibility, efficacy, and safety of laparoscopy in diagnosis and treatment of recurrent small bowel obstruction. Methods Retrospective analysis of 253 patients who underwent therapeutic laparoscopy for recurrent small bowel obstruction from June 1996 to May 2005 was carried out. Patients with acute small bowel obstruction, bowel obstruction due to tumor, and obstructed inguinal hernias were excluded from analysis. Results Laparoscopy diagnosed cause of obstruction in all except 3 (1.18%) patients. The etiology included adhesions (38%), incarcerated ventral incisional hernias (32%), Meckel diverticulum (7%), stricture (14%), volvulus (3%), intussusception (4%). One hundred sixty nine patients were managed totally laparoscopically with adhesiolysis. Therapeutic bowel intervention other than adhesiolysis was required in 84 patients, of which 33 procedures were performed totally laparoscopically and remaining 51 procedures were completed with laparoscopically guided target incision. Five patients required conversion to open celiotomy. Iatrogenic enterotomies occurred in 3 patients and small bowel perforation during manipulation occurred in 1 patient. Postoperative procedure-related complications were seen in 44 patients. There was one mortality due to postoperative arrhythmia and cardiac failure. Conclusions Laparoscopic diagnosis and treatment of recurrent small bowel obstruction is feasible, safe, and can be performed electively in selected cases.

Splenectomy is increasingly being performed by various minimal access surgical modalities for select hematologic disorders.A retrospective analysis was performed on the first 50 patients on whom laparoscopic splenectomy (LS) was attempted. The data studied included indications for surgery, patient demographics, intraoperative parameters, and patient outcomes. A total laparoscopic approach (TLS) was employed in 38 patients and a hand-assisted technique (HALS) was used in 12 patients with massive splenomegaly. Eight patients had concomitant surgical procedures: 7 patients underwent laparoscopic cholecystectomy and 1 patient received a kidney transplant. The most common indications for LS were idiopathic thrombocytopenic purpura (ITP) (50%) and hereditary spherocytosis (24%).LS was successfully completed in 48 patients (96%). Thirty-four patients (68%) required perioperative blood or platelet transfusions. The mean spleen diameter was 17.1 cm (range, 11.2-28.4 cm) on imaging study and mean intact splenic weight was 1019 gm. The mean operative time was 188 minutes (range, 90-340 minutes) in the TLS group and 171 minutes (range, 120-240 minutes) in the HALS group. The mean intraoperative blood loss was 306 mL (range, 40-640 mL) in the TLS group and 163 mL (range, 100-300 mL) in the HALS group. The mean postoperative hospital stay was 3.2 days (range, 2-5 days).TLS is safe and feasible in patients with nonpalpable spleens. A concomitant laparoscopic procedure for treating coexisting abdominal pathology may be performed without additional morbidity. The HALS technique may be preferable in patients with splenomegaly (palpable spleens), as it appears to offer intraoperative advantages for retraction, dissection, hemostasis, and organ retrieval.

Lumbar hernias need to be repaired due to the risk of incarceration and strangulation. A laparoscopic intraperitoneal approach in the modified flank position causes the intraperitoneal viscera to be displaced medially away from the hernia. The creation of a wide peritoneal flap around the hernial defect helps in mobilization of the colon, increased length of margin is available for coverage of mesh and more importantly for secure fixation of the mesh under vision to the underlying fascia. Laparoscopic lumbar hernia repair by this technique is a tensionless repair that diffuses total intra-abdominal pressure on each square inch of implanted mesh. The technique follows current principles of hernia repair and appears to confer all benefits of a minimal access approach.

An obturator hernia is a rare hernia that is bilateral in about 6% of patients. Most patients present with chronic pelvic pain although a few patients may present with features of intestinal obstruction. Only about 10% of obturator hernias are diagnosed preoperatively.A 65-year-old female patient with chronic obstructive pulmonary disease presented with bilateral groin swellings associated with local pain and heaviness. She also suffered from recurrent episodes of abdominal distension. She was diagnosed to have bilateral direct inguinal hernias and a left femoral hernia. At endoscopy under epidural anesthesia she was found to have a direct inguinal, an indirect inguinal, and a femoral hernia on the left side and an indirect inguinal hernia on the right side. Additionally, the endoscopic totally extraperitoneal approach to inguinal hernias identified hitherto undiagnosed bilateral obturator hernias. The hernias were reduced and polypropylene mesh was placed bilaterally covering the myopectineal orifice and pelvic floor bilaterally.The patient was discharged the next day and is symptom-free on followup at eight months.Endoscopic repair of groin hernias allows the surgeon not only to diagnose and treat unsuspected groin hernias but also allows identification, dissection, and repair of coincidental occult pelvic hernias like obturator hernias at the same time.

With advancements in minimal access surgery, combined laparoscopic procedures are now being performed for treating coexisting abdominal pathologies at the same surgery. In our center, we performed 145 combined surgical procedures from January 1999 to December 2002. Of the 145 procedures, 130 were combined laparoscopic/endoscopic procedures and 15 were open procedures combined with endoscopic procedures. The combination included laparoscopic cholecystectomy, various hernia repairs, and gynecological procedures like hysterectomy, salpingectomy, ovarian cystectomy, tubal ligation, urological procedures, fundoplication, splenectomy, hemicolectomy, and cystogastrostomy. In the same period, 40 patients who had undergone laparoscopic cholecystectomy and 40 patients who had undergone ventral hernia repair were randomly selected for comparison of intraoperative outcomes with a combined procedure group. All the combined surgical procedures were performed successfully. The most common procedure was laparoscopic cholecystectomy with another endoscopic procedure in 129 patients. The mean operative time was 100 minutes (range 30-280 minutes). The longest time was taken for the patient who had undergone laparoscopic splenectomy with renal transplant (280 minutes). The mean hospital stay was 3.2 days (range 1-21 days). The pain experienced in the postoperative period measured on the visual analogue scale ranged from 2 to 5 with a mean of 3.1. Of 145 patients who underwent combined surgical procedures, 5 patients developed fever in the immediate postoperative period, 7 patients had port site hematoma, 5 patients developed wound sepsis, and 10 patients had urinary retention. As long as the basic surgical principles and indications for combined procedures are adhered to, more patients with concomitant pathologies can enjoy the benefit of minimal access surgery. Minimal access surgery is feasible and appears to have several advantages in simultaneous management of two different coexisting pathologies without significant addition in postoperative morbidity and hospital stay.

Surgery has remained the mainstay for the treatment of hydatid cyst. The rapid development of laparoscopic techniques has encouraged surgeons to replicate principles of conventional hydatid surgery using a minimally invasive approach. Several reports have confirmed the feasibility of laparoscopic hepatic hydatid surgery. We report the use of a laparoscopic approach for cysts located in the liver, lung, and retroperitoneum. Fifteen patients with hydatid cysts, including one patient with a recurrent cyst, of various organs, including the liver, lung, and retroperitoneum, were operated on laparoscopically. Sixteen hydatid cysts were drained in a total of 15 patients. The mean operative time was 84 +/- 6 minutes (60-125 minutes). The mean duration of the hospital stay was 2.3 days (1-6 days). The mean cyst diameter was 9.2 cm (6.4-13.5 cm). No conversions to open surgery were required. One complication, a trocar-induced bowel perforation, occurred, and there was no mortality. During 3 to 44 months (mean, 27 months) of follow-up, no recurrences developed. Minimal access surgery is a safe, effective, and viable option for the management of selected patients with hydatid cysts in various locations, such as the liver, lung, and retroperitoneum.

A retrospective study was conducted to identify the reasons for recurrence following endoscopic total extraperitoneal (TEP) repair of inguinal hernias and to develop a strategy to prevent recurrence.Between January 1996 and December 2001, 1193 TEP hernia repairs were performed in 694 patients. Following reduction of the hernia sac and dissection of the preperitoneal space up to the psoas muscles laterally, a Prolene mesh (15 x 15 cm) was placed. The mesh was fixed medially to the Cooper ligament with two or three spiral tacks. In six patients, the hernia recurred following endoscopic TEP repair within the same period. Four of these patients elected to undergo laparoscopic transabdominal preperitoneal (TAPP) repair of the recurrent hernia.Medial recurrences developed in three of the four patients because of medial displacement of the mesh. One patient was found to have a missed indirect hernia sac. All the patients who underwent laparoscopic TAPP repair had an uneventful recovery and are well at follow-up.In addition to medial fixation of the mesh to the Cooper ligament, complete proximal dissection of the peritoneum from the spermatic cord and additional fixation of the mesh to the anterior abdominal wall, with careful avoidance of possible injury to the adjacent nerves, may prevent recurrences.

Paravertebral and paraspinal tumors in the posterior mediastinum are predominantly neurogenic in origin. The treatment comprises surgical extirpation. We report a case of a 40-year-old man with a 2-month history of pain epigastrium, radiating to the left scapula, and marked (10 kg) weight loss. Preoperative CT scan showed a paraspinal mass 8 cm in diameter at the level of the tenth thoracic vertebra. A CT scan-guided fine-needle aspiration cytologic analysis revealed the mass to be of neurogenic origin. Transabdominal laparoscopic excision of this lower posterior mediastinal neurogenic tumor was attempted and accomplished safely. The approach was through the left crural fibers, which were split to access the lower posterior mediastinum. Operating time was 122 minutes. Postoperatively, a left intercostal drain was inserted. The patient was discharged on the third postoperative day, after intercostal drain removal. Lower posterior mediastinal paraspinal tumors can be resected laparoscopically with careful preoperative investigation for tumor localization and a meticulous laparoscopic technique. A major advantage of transabdominal laparoscopic resection, as compared with open or thoracoscopic (VATS) excision, is that the patient recovers rapidly with minimal operative and anesthetic morbidity.

Jejunoileal diverticulae, also referred to as non-Meckelian diverticulae, are very uncommon. These diverticulae are considered to be acquired pulsion diverticulae and they mostly occur in older people. Their prevalence increases with age. About 80% of these diverticulae occur in jejunum and are usually multiple. Patients with jejunoileal diverticulae present with nonspecific symptoms. The clinical picture of a complicated jejunoileal diverticulae can be confused with other intra-abdominal acute conditions such as appendicitis, cholecystitis, perforated ulcer, etc. Nonmechanical or pseudoobstruction is related to the dyskinesia associated with this condition. The diagnosis is made by a small bowel contrast study, enteroclysis, endoscopy or computed tomography. A surgical approach is the best form of treatment for complicated jejunoileal diverticulae. Laparoscopy is very useful in diagnosing and treating this condition. The current report is about a patient who presented with recurrent subacute intestinal obstruction and was managed by laparoscopy.

Of the various traumatic injuries associated with blunt abdominal trauma, traumatic hernias form a rare and small group. We present a case report of a hernia in the psoas muscle in a 26-year-old lady diagnosed during extraperitoneal repair for inguinal hernia. The hernia was managed laparoscopically by reduction of contents and mesh placement over the defect. This is the first such case reported in the literature till date.

Laparoscopic cholecystectomy is the gold standard for gallbladder removal and the most common laparoscopic procedure worldwide. With the advent of laparoscopic surgery and its continuous development, the focus has shifted to ‘scarless’ surgery. In recent times, the innovative technique of single-incision laparoscopic surgery (SILS) has been applied in gallbladder removal and even more complex biliopancreatic procedures to further minimize the invasiveness of the surgery. Newer developments in laparoscopic equipments and instrumentation have helped to further evolve this field of minimally invasive surgery. Literature search was performed using the following online search engines: Google, Medline, PubMed, Cochrane, and the online Springer link library. The terms used for the search were as follows: SILS, LESS, single-incision laparoscopic surgery, single-port laparoscopic surgery, SILS cholecystectomy, and SILS pancreatic surgery. Articles that matched the search criteria were selected and extensively reviewed. Moreover, pertinent information on instrumentation and technology for SILS and LESS was obtained by accessing websites of manufacturers. Although SILS represents the search for an essentially scarless surgery, there is still not a widespread use and uniformity of this procedure. SILS is performed either by single- or multiple-port technique. In the present article, we present a review of the potential benefits, limitations, and risks of SILS in biliary and pancreatic diseases. There are many studies showing benefits in cholecystectomy. A few case reports have also emerged about its feasibility in procedures such as cystogastrostomy and limited pancreatic resection. Further research and development of this technique is needed to arrive at a tangible conclusion about the perceived benefits of SILS. Randomized studies to compare SILS with traditional laparoscopy are essential.

Agenesis of gallbladder is a rare congenital anomaly. Variable diagnostic approaches, perioperative management strategies and postoperative follow up protocols provide a dilemma to its correct diagnosis and management.We hereby present five patients with agenesis of gallbladder encountered in our institution between 1992 to 2008. Four out of five patients had symptoms suggestive of gallstones including upper abdominal pain and acid dyspepsia, which were further substantiated by ultrasound reports showing shrunken contracted gallbladder with calculi.On laparoscopy the gallbladder was absent in all five patients leading to conversion to laparotomy in the initial three patients. With increasing experience, the next two patients were diagnosed conclusively by laparoscopy to have agenesis of gallbladder, without the need for conversion which was further confirmed by post operative imaging studies.Gallbladder agenesis is rarely encountered in clinical practice. With increased experience in laparoscopy, the condition no longer mandates conversion to laparotomy for confirmation of diagnosis. Symptomatic improvement occurs in all patients following surgical intervention.

Obesity has been observed to be on the rise in the Indian subcontinent. We report our early experience with the laparoscopic sleeve gastrectomy (LSG) for treating morbid obesity in the Indian population along with description of the surgical technique.The data of 75 patients who underwent LSG for the treatment of morbid obesity at the Minimal Access, Metabolic and Bariatric Surgery Centre, Sir Ganga Ram Hospital, Delhi, from November 2006 to February 2009, were retrospectively reviewed from prospective database. The gastric sleeve is created laparoscopically using sequential firings of a linear stapling device applied alongside a 36-Fr calibrating bougie. The data collected included age, gender, initial body mass index (BMI) and excess weight, the co-morbidity status, and preoperative investigations. Perioperative parameters and follow-up details [weight, BMI, excess weight loss (%EWL), resolution of co-morbidities, and postoperative investigations] were noted.All procedures were completed laparoscopically. There was no major procedure-related morbidity. Hemorrhage requiring blood transfusion was observed in four patients. One patient died at 2 weeks postoperatively due to pulmonary embolism. There was a steady rise in %EWL from 31.2% at 3 months to 52.3% at 6 months, 59.13% at 1 year, and 65% at 2 years. Type II diabetes was resolved in 81.2%, hypertension in 93.75%, and dyslipidemia in 85% at 1 year.Although long-term results are necessary to determine the benefits of the procedure, early results indicate that LSG may be a safe and feasible option for treating the morbidly obese patients.

Laparoscopy has become the standard surgical approach to surgery for gastrooesophageal reflux disease (GERD) and hiatal hernia repair with excellent long-term results and high patient satisfaction. However several studies have shown that hiatal hernia repair, especially large hiatus are associated with high recurrence rate. Mesh reinforcement has been proposed for repair of large hiatus hernia. The objective of this study was to evaluate the role of mesh cruroplasty in management of large hiatus hernia (5 cm).Between February 2002 to December 2007, 73 patients (28 men and 45 women) who underwent laparoscopic hiatal hernia repair with mesh cruroplasty were included in our study. Mesh reinforcement (cruroplasty) was used for repair of large hiatus hernia (5 cms hernial defect). Mean age was 50.4 years (range 30-72 years). Follow up included barium swallow of patients at 3 months and yearly thereafter.Seventy-three patients underwent mesh cruroplasty for large hiatus hernia. We were able to adequately mobilise the oesophagus to achieve an intra-abdominal length of at least 3 cm in all patients. Intraoperative complication rate was 8.21% (6/73), intraoperative complications included pleural tear, bleeding from splenic capsule laceration and short gastric vessels. Postoperative complication rate was 4.1% (3/73), which included complete dyspahgia, atelactasis and pneumonia. Mean duration of hospitalisation was 3.5 days (range 3-9 days). Five patients (5/73) were lost to follow up. Four patients (5.8%) developed recurrence on routine follow up. No mesh related complications were noted on long-term follow up period. Mean follow up period was 3.2 years (range 5 months-6 years).Our data supports the use of mesh in hiatal hernia repair, especially in large hiatus hernia as it leads to low recurrence rates. Longer follow up and more randomised controlled trials are needed to establish laparoscopic mesh cruroplasty as standard technique for large hiatal hernia repair.

To analyze patient demographics, pathology, surgical procedure and outcome in initial 24 consecutive patients who underwent laparoscopic adrenalectomy in our department.Twenty four patients underwent laparoscopic adrenalectomy between September 2000 and August 2005. There were 12 males and 12 females with a mean age of 44.6 years (range 25-68 years). The indications for adrenalectomy were pheochromocytoma (13 patients), Cushing's syndrome (5 patients), myelolipoma (2 patients), adrenal cyst (2 patients), aldosteronoma (1 patient) and adrenal incidentaloma (1 patient). Nineteen of our patients with functioning adrenal tumours were prepared preoperatively for periods ranging up to 2 weeks by the endocrinologist. All laparoscopic adrenalectomies were performed via lateral transperitoneal approach using standard four-port technique. Patients with pheochromocytoma and Cushing's syndrome were monitored in the surgical intensive care unit during immediate postoperative period. The clinical and intraoperative characteristics, complications and outcomes of all patients were analyzed.The mean operative time for laparoscopic adrenalectomy was 136 minutes. Intraoperative hypertension occurred in 8 patients. Intraoperative hypotension occurred in 2 patients. One patient required conversion due to dense adhesions and hemorrhage. Postoperative complications were seen in six patients - immediate postoperative hypotension (2 patients), features of steroid withdrawal (2 patients) and postoperative pyrexia (2 patients). Five patients with pheochromocytoma required antihypertensive drugs in the postoperative period. There was no mortality in our series.Laparoscopic adrenalectomy is a safe operation that incorporates all the benefits of minimal access surgery and is associated with a satisfactory postoperative outcome. A careful preoperative preparation in functioning adrenal tumours aids in the faster recovery of these patients.

Mesh migration after laparoscopic inguinal hernia repair is an unusual complication. We report a case of a 45-year-old man with persistent discharging of abdominal wall sinus after total extraperitoneal inguinal hernia repair. The patient underwent exploration and excision of the sinus tract with removal of the embedded mesh. A part of the mesh had migrated into the urinary bladder. Partial cystectomy with excision of wall containing the mesh was performed.

Hydatid cyst is a significant health problem in endemic regions. Although progress has been made in medical treatment and interventional radiology techniques, surgery is currently the treatment of choice. The hydatid cysts are known to occur at several unusual sites in the body. With increasing experience in laparoscopy and retroperitoneoscopy, attempts have been made to offer the advantages of minimal access procedures to hydatid disease patients. We present a case report of such a patient whose retroperitoneal hydatid cyst was removed endoscopically.

Laparoscopic repair of ventral abdominal wall hernias involves intraperitoneal placement of a mesh, which may lead to adhesion formation and bowel fistulation. The first series of selected patients with ventral abdominal wall hernias treated laparoscopically by extraperitoneal placement of a polypropylene mesh is presented. Thirty-four patients (24 women and 10 men; median age, 52 years [range, 34-70]) were selected from among 122 patients undergoing laparoscopic ventral hernia repair. Of these patients, 18 had a primary ventral abdominal wall hernia and 16 had an incisional hernia. After reduction of sac contents and adhesiolysis intraperitoneally, a large flap of peritoneum (with extraperitoneal fat, fascia, and posterior rectus sheath where present) was raised to accommodate a suitably sized polypropylene mesh, which was then covered again with the peritoneal flap at the end of the procedure. Intraoperatively, apart from circumcision of the hernial sac at the neck, a total of 24 iatrogenic peritoneal tears occurred in 20 patients, mainly at the site of the previous scar. In two patients, it was observed that greater than 25% of the mesh was exposed after the procedure. The median (+/-SD) duration of hospitalization postoperatively was 1 day (+/-0.56). One patient's hernia recurred 4 months after surgery, and one patient's infected mesh was removed 8 months after surgery. Laparoscopic extraperitoneal placement of a mesh is feasible and appears to be an advance over laparoscopic intraperitoneal mesh placement for ventral abdominal wall hernias in selected patients. However, longer follow-up and controlled clinical trials will be necessary before any firm conclusions can be drawn.

We report a 65-year-old man presenting with acute pain in the abdomen. Diagnostic laparoscopy revealed gangrenous torsion in one of the appendices epiploicae in the ascending colon. This was excised with harmonic scalpel.

Background: Choledochal cyst is a rare congenital anomaly of the biliary tract. With increased familiarity with the laparoscopic anatomy of the biliary tract and advances in minimally invasive techniques, surgeons have ventured further to operate on technically difficult cases such as choledochal cyst that were until recently managed by laparotomy. Patients and Methods: We present our experience with two female patients aged 14 years and 26 years with choledochal cyst (type I according to the Alonzo-Lej classification) that were successfully excised with construction of a Roux-en-Y hepaticojejunostomy entirely laparoscopically. Results: Both patients had an uneventful recovery, with no major morbidity. The first patient had a bile leak, which resolved over 5 days. Both were discharged by the 5th postoperative day. Conclusion: Laparoscopic management of choledochal cyst is feasible although technically difficult and may be performed in specialized institutes dealing with advanced laparoscopic surgery.

Ingestion of foreign body is a serious problem commonly encountered in our clinical practice. Most of them pass spontaneously, whereas in others endoscopic or surgical intervention is required because of complications or non-passage from the gastrointestinal tract. We present here a case of teaspoon ingestion, which did not pass spontaneously. Laparoscopic retrieval of teaspoon was done from mid jejunum after enterotomy and the patient recovered uneventfully. Right intervention at the right time is of paramount importance.

Mature symptomatic pancreatic pseudocysts require surgical intervention for their management. In this era of minimal access surgery, several reports are now available of laparoscopic management of pancreatic pseudocysts.We have performed this procedure in five patients over the past 2 years. Four patients developed the pseudocyst after acute alcoholic pancreatitis and one following acute biliary pancreatitis. The diameter of the pseudocyst ranged from 8 to 12 cm. The procedure was performed using five ports. The Harmonic Scalpel was used to create two ports in the anterior stomach wall through which two balloon trocars were placed into the gastric lumen. Following balloon inflation, the trocars were used to lift up the anterior gastric wall. This created the space for the cystogastrostomy to be fashioned laparoscopically through the balloon trocar. The ball probe of the Harmonic Scalpel was used to puncture the cyst through the posterior gastric wall. The cystogastrostomy was completed by firing an Endo-GIA30 stapler across the fused posterior gastric wall and anterior wall of the cyst.The mean operative time was 90 minutes (range 80-125 minutes). The mean postoperative stay was 3.0 days. One patient had intraoperative bleeding at the anastomotic site, which was easily controlled.Laparoscopic cystogastrostomy offers a feasible and safe therapeutic option for selected patients with large symptomatic pancreatic pseudocysts.

Spigelian hernia occurs through slit like defect in the anterior abdominal wall adjacent to the semilunar line. Most of spigelian hernias occur in the lower abdomen where the posterior sheath is deficient. The hernia ring is a well-defined defect in the transverses aponeurosis. The hernial sac, surrounded by extraperitoneal fatty tissue, is often interparietal passing through the transversus and the internal oblique aponeuroses and then spreading out beneath the intact aponeurosis of the external oblique. Spigelian hernia is in itself very rare and more over it is difficult to diagnose clinically. It has been estimated that it constitutes 0.12% of abdominal wall hernias. The spigelian hernia has been repaired by both conventional and laparoscopic approach. Laparoscopic management of spigelian hernia is well established. Most of the authors have managed it by transperitoneal approach either by placing the mesh in intraperitoneal position or by raising the peritoneal flap and placing the mesh in extraperitoneal space. There have also been case reports of management of spigelian hernia by total extraperitoneal approach. We retrospectively reviewed our experience of ten patients between 1997 and 2007. Eight patients (8/10) presented with abdominal pain and two patients (2/10) were asymptomatic. In six patients (6/10) we performed an intraperitoneal onlay IPOM repair, in two patients (2/10) transabdominal preperitoneal repair (TAPP), and in two (2/10) total extraperitoneal repair (TEP). There were no recurrences, or other morbidity at mean follow up period of 3.2 years (range 6 months to 10 years).

Inguinal hernia surgery has been one of the most extensively debated and continues to evolve in search for the ideal technique. Even though the method to diagnose hernia has largely remained clinical, recently other modalities have detected hernias that are not picked up on clinical examination or are incorrectly labeled. Laparoscopy, for the first time has given surgeons the unique opportunity to look at both sides of the groin and to detect and study the contra lateral groin in a patient of clinically unilateral hernia. This has given rise to some interesting findings. In the pediatric age group the value of bilateral detection and repair has been extensively debated. However, the same is not true for the adults despite the facts that there are better methods for detection, better understanding of pathogenesis of hernia and better repair techniques that can take care of bilateral repair without adding to morbidity. That hernia is not a simple derivative of patent processus vaginalis or strain related cause is beginning to be better understood now. It may primarily be a disorder of collagen metabolism with genetic basis. Laparoscopy has also made us wiser in detection of type of hernia and examination of both groin areas. In several studies there have been a high percentage of undetected hernias or additional defects. This was never realized earlier as in open surgery there is no question of exploring the asymptomatic groin. Laparoscopy in bilateral repair is safe and does not add significantly to the operating time, cost or morbidity. At our Department of Minimal Access Surgery, Sir Ganga Ram Hospital, New Delhi, India we have been performing Endoscopic Totally Extraperitoneal (TEP) repair for all simple and complicated inguinal hernia since 1994. We now routinely perform a bilateral repair based on our understanding that the pathogenesis of hernia is a complex process and any genetic basis of collagen disorder has to affect the patient bilaterally. The clinical examination may have unacceptably low sensitivity. Early identification and repair obviates the need for reoperation, reduces overall costs and eliminates further anaesthetic and operative risks for the patient
