Objective: Clinical treatment strategies and progress metrics for patients with inducible laryngeal obstruction (ILO) and exercise-induced laryngeal obstruction (EILO) have not been systematically applied across clinics. The goals of this review were to identify the intervention strategies used to treat upper airway disorders and determine the clinical metrics by which improvement or resolution of ILO/EILO is determined in clinical studies of speech-language pathology intervention., Method: A systematic review was conducted using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Systematic Reviews Checklist. English language, full-text publications were identified through MEDLINE (Ovid), APA PsycINFO, and Web of Science for publications that described clinical outcomes following behavioral treatment for ILO provided by a speech-language pathologist (SLP)., Results: A total of 238 sources were retrieved, of which 75 were duplicates. Titles and abstracts of 163 were screened, with 22 sources included for full-text review. Citation review yielded nine additional resources. Thirty-one sources were included for data extraction. Most sources described use of respiratory/laryngeal retraining. There was a lack of consistency for clinical and standardized metrics used to evaluate improvement or resolution of upper airway symptoms., Conclusions: Behavioral and standardized outcome metrics for evaluating therapy outcomes from SLP behavioral intervention of ILO/EILO are not consistently applied. Clinical metrics standards for clinicians are needed to provide a means to evaluate graded improvement in treatment and changes in health care utilization as well as for training less-experienced clinicians., Supplemental Material: https://doi.org/10.23641/asha.27172683.

Background: The evaluation of AIDS patients with acute abdominal complaints (AAC) is quite difficult, and surgical intervention is associated with a high complication rate. The intent of this study is to evaluate the application of laparoscopy in the diagnosis and treatment of AIDS patients with AAC., Methods: This is a retrospective analysis of 10 consecutive AIDS patients who presented with AAC. Each had evaluation by a surgical team with subsequent laparoscopic intervention. The charts were reviewed for age, sex, time with AIDS, AIDS comorbidities, evaluation modalities, findings, treatment modalities, and outcome., Results: Laparoscopy resulted in the successful surgical treatment of four patients, diagnosis of medically treatable conditions in four patients, and alteration of the incision site in the remaining two patients. Each patient thus received direct benefit from laparoscopy. Two complications, in the converted patients, and no mortalities were encountered., Conclusions: Laparoscopy is a safe and effective interventional modality in the diagnosis and treatment of AAC in the AIDS patient.

In children, intussusception is a common cause of intestinal obstruction. In contrast, intussusception in the adult is an infrequent cause of intestinal obstruction and in the majority of instances has some obvious cause such as a tumor forming the lead point of the intussusceptum. Diagnosis is suggested by chronic, intermittent symptoms of intestinal obstruction, the presence of an abdominal mass, and the passage of blood per rectum. In contrast to children, treatment is invariably surgical resection without reduction. We have encountered an appendiceal intussusception as a manifestation of a mucinous cystadenoma of the appendix. There was no evidence of pelvic visceral involvement. This unique presentation is rarely reported. The patient underwent uneventful laparoscopy-assisted segmental ileocolonic resection with stapled anastomosis. An analysis of our diagnostic and therapeutic approach, as well as a review of appendiceal pathology as a cause of intussusception are presented to better understand this rare clinical entity.

At Georgia Baptist Medical Center, a community-based, university-affiliated hospital, we adopted the total extraperitoneal approach (TEPA) to laparoscopic herniorrhaphy due to potential complications in entering the abdominal cavity reported previously with the transabdominal preperitoneal technique (Am Surg 1996;62:69-72). We have also employed regional anesthesia (epidural) in 108 patients in whom the TEPA was utilized. In our institution, the TEPA has compared favorably to the transabdominal preperitoneal technique, with lower complication and recurrence rates. In patients with previous lower abdominal surgery, the TEPA is considered a relative contraindication due to the increased risk of complications (Am Surg 1997, in press). Since June 1993, we have performed 503 laparoscopic herniorrhaphies using the TEPA, with encouraging early results. To date, two recurrences have been reported, one with previous lower abdominal surgery and another whose recurrence was noted to be secondary to incomplete reapproximation of the mesh with staples around the cord structures. Four major complications include two bowel perforations and two cystotomies noted during balloon dissection of the preperitoneal space. Three of these patients had previous lower abdominal surgery. Epidural anesthesia was used in 108 patients, 4 of whom required conversion to general anesthesia due to peritoneal tears and pain associated with pneumoperitoneum. All four of these patients had previous lower abdominal surgery. In summary, the TEPA remains a viable technique for laparoscopic herniorrhaphy with acceptable complication and recurrence rates. Epidural anesthesia is well tolerated by the patients undergoing this particular repair. We feel that lower abdominal surgery may be a mitigating factor in selection of the TEPA. Continued re-evaluation of the procedure is warranted before definitive conclusions can be made.

In an attempt to obviate the need for an incision the length of the leg during in situ saphenous vein bypass, a minimally invasive operation using 'laparoscopic techniques' was developed. At operation, standard incisions were made over the proximal femoral artery/vein and the saphenous vein at the distal popliteal artery level. An angioscopic valvulotome was used to perform valvulotomy under direct vision. After valvulotomy, a distention balloon system was used to form a 'pocket' into which a laparoscope was inserted. Trocars were then inserted under direct vision and the saphenous vein dissected and side branches individually clipped. After occlusion of the venous side branches, proximal and distal arterial anastomoses were performed in the standard fashion. This minimally invasive operation using laparoscopic techniques precludes the need for a long leg incision and saphenous vein dissection, except at the proximal and distal arterial anastomoses.

Percutaneous drainage of an intra-abdominal abscess is utilized frequently. To evaluate its effectiveness at our institution over 16 months, 18 patients (mean age 49 years) who underwent radiologically directed percutaneous drainage of intra-abdominal abscesses were retrospectively reviewed. The abscesses were postoperative in 14 patients (laparotomy, 5; appendectomy, 4; colectomy, 3; hysterectomy, 2). Primary abscesses were due to diverticular disease (3), perforated appendicitis (3), perforated colon carcinoma (1), and perforated peptic ulcer (1). Percutaneous drainage was ultimately established in all patients with complete resolution of the abscesses occurring in 12 patients (67%). The average duration for drainage was 5.5 days (range 1-23). Average length of hospital stay after the establishment of drainage was 14.6 days (range 1-48). Six patients required surgical procedures because of inadequate abscess drainage (4) or continued clinical deterioration (2). There were no deaths. A major complication (colon perforation, enteric fistula) occurred in two patients (11%). Catheter-related problems were common (7/18 patients), and included drain migration (3), inadequate drainage, and catheter obstruction(2). Four patients required multiple percutaneous drainage procedures. Despite technical feasibility and clinical success in the majority of patients, percutaneous drainage of these intra-abdominal abscesses had frequent catheter-related complications. One-third of patients (31.8%) required surgical intervention despite a prolonged period (average 15 days) of percutaneous drainage. Patients demonstrated to have nonresolving abscesses by computer tomography (CT), abscesses associated with colonic diverticular disease of colon cancer, and abscesses localized to the left lower quadrant were noted to have less successful percutaneous abscess drainage. Patients with a persistent of rising leukocyte count and/or an elevated APACHE II score prior to drainage should be routinely reevaluated at 4 days. Earlier surgical intervention is felt to be warranted because these two factors in this study were indicative of a low nonoperative success rate. Post-appendectomy abscesses uniformly demonstrated prompt response to percutaneous drainage. CT-directed percutaneous drainage of intra-abdominal abscesses provides an alternative to immediate surgical intervention. The preliminary findings from this study suggest a limited application of this intervention in one-third of patients. Further detailed analysis of this patient group is required to delineate guidelines for identifying those patients where percutaneous drainage is unlikely to be successful.

Between April 1991 and April 1994, 500 laparoscopic herniorrhaphies have been performed at our institution. The transabdominal preperitoneal approach was used for 290 repairs, and the total extraperitoneal approach was used for 210 repairs. Although both repairs resulted in acceptable recurrence and complication rates, we adopted the total extraperitoneal approach in June 1993, with a resulting lower recurrence rate (0.5% versus 2.1%) and lower complication rate (3.1% versus 11.1%) when compared with the transabdominal approach. In this retrospective review, four epigastric vessel injuries (1.6%) and one bowel obstruction from a port hernia (0.5%) were attributed to the lateral port placement in the transabdominal approach. There were also two visceral injuries (1.0%) from entering the abdominal cavity in the transabdominal approach. The one visceral injury (0.6%) in the total extraperitoneal approach was a result of the balloon dissection in a patient with multiple previous lower abdominal operations. Better exposure and lateral visualization of the extraperitoneal space has led to less incidence of nerve injury (0.0% versus 2.4%) and a lower recurrence rate (0.5% versus 2.1%) in the total extraperitoneal approach. The total extraperitoneal approach to laparoscopic herniorrhaphy compares favorably to the transabdominal approach in our institution. The improved results may have been due to the technical differences between these approaches.

To determine the technical feasibility and success of laparoscopic fundoplication in the treatment of severe gastroesophageal reflux disease (GERD), 18 consecutive adult patients were enrolled in a prospective study. All patients had received unsuccessful conservative treatment, were refractory to medical management, or had recurrence of symptoms of esophagitis after omeprazole therapy. All patients had severe acid reflux on 24-hour esophageal pH monitoring, endoscopic evidence of previous or ongoing esophagitis, and a defective lower esophageal sphincter on manometry. Complete (Nissen) fundoplication was done in 11 and partial (Toupet) fundoplication in 7 patients; the mean operative time was 183 minutes (range, 120 to 357 minutes). Feedings were initiated on the first postoperative day, and the average length of stay was 2.6 days (range, 1 to 6). There were no deaths or conversions to laparotomy. Postoperative morbidity consisted of transient bloating in three patients and dysphagia requiring dilatation in four patients. Return to work or normal activity averaged 19 days (range, 3 to 28), and 17 patients (94%) reported good to excellent results, with a median follow-up of 7 months. Laparoscopic fundoplication is technically feasible and offers a sound surgical alternative to patients with refractory GERD, but longitudinal follow-up is required to confirm long-term results.

Background: There are a variety of accepted techniques for herniorrhaphy. With the advent of laparoscopic general surgery, new endoscopic techniques using the transabdominal and total extraperitoneal approaches have been added to the many options for the repair of inguinal hernia. The purpose of this study was to compare the early results of these approaches at a single institution., Methods: Between May 1991 and August 1994, 600 laparoscopic herniorrhaphies were performed on 493 patients. Three hundred hernias were repaired using the transabdominal preperitoneal approach and 300 were repaired using the total extraperitoneal approach. A retrospective review was performed with emphasis on the comparison of recurrence rates and complication rates between these two approaches to laparoscopic herniorrhaphy., Results: The recurrence rates were 2.0% (6/300) for the transabdominal approach and 0.3% (1/300) for the total extraperitoneal approach. The complication rate for the transabdominal approach was 10.7% and included thigh paresthesias (6), inferior epigastric artery injuries (4), enterotomy (1), bowel obstruction (1), bladder injury (1), and urinary retention (14). The complication rate for the total extraperitoneal approach was 3.7% and included enterotomies (2), bladder injury (1), paresthesia (1), and urinary retention (6). The recurrence, the enterotomies, and the bladder injury in the total extraperitoneal group were all in patients who had previous lower abdominal operations., Conclusions: Although both the transabdominal preperitoneal and total extraperitoneal approaches to laparoscopic herniorrhaphy have acceptable recurrence and complication rates, there were significant advantages to the total extraperitoneal approach in our institution. Previous lower abdominal surgery may be a relative contraindication to the total extraperitoneal approach.

There are a variety of accepted techniques for herniorrhaphy. With the advent of laparoscopic general surgery, laparoscopic transabdominal and total extraperitoneal techniques have been added to the many options for repair of the inguinal hernia. From 5/91 to 6/93 we had performed 290 transabdominal preperitoneal (TAPP) laparoscopic herniorrhaphies on 244 adult patients. Due to concerns of potential early and late complications associated with entering the abdominal cavity, we adopted the total extraperitoneal approach (TEPA) for laparoscopic herniorrhaphies in 6/93. Between 6/93 and 12/93, 118 hernias have been repaired in 95 patients using the total extraperitoneal approach. In a retrospective comparison between these two procedures, the recurrence rate is 1.7% (5/290) for TAPP herniorrhaphies and 0% (0/118) for the TEPA. The overall complication rate for TAPP herniorrhaphies was 11.1% and included thigh paresthesias (6), inferior epigastric artery injuries (4), enterotomy (1), bowel obstruction (1), bladder injury (1), and urinary retention (14). The overall complication rate for the TEPA was 3.2% and included bladder injury (1), and urinary retention (2). Mean operative time was similar between these groups (TAPP-81.2 minutes, TEPA-92.9 minutes).

In order to help determine the risks and benefits, we retrospectively analyzed the results of our first 114 laparoscopically assisted bowel procedures. Procedures performed consisted of partial colectomy (85), total or subtotal abdominal colectomy (8), total proctocolectomy with J-pouch ileal reservoir (11), and diverting procedures (10). Forty-nine procedures were for malignancy. The rate of conversion to laparotomy was 13.2%. Oral feedings were resumed in 2.4 days (range 1-5), and bowel function returned in 3.8 days (range 2-8). The average length of stay was 4.2 days for partial colectomy and 6 days for total, subtotal, and proctocolectomy. The mean return to normal activity for all groups was 16.7 days (10.8 days for partial colectomy). There were no deaths. Major morbidity (6%) consisted of abscess (3), anastomotic leak (2), and hemorrhage (1). Mean operative costs analyzed for the initial 37 patients were higher for laparoscopic colectomies when compared to traditional colectomies; however, the mean total hospital costs were less for the laparoscopic procedures. These data suggest that the laparoscopic approach to colorectal resection is an acceptable alternative to laparotomy for a variety of disease processes, allowing patients an early return to normal activity.

Laparoscopic herniorrhaphy continues to gain popularity, but should be subjected to proper scrutiny before widespread acceptance. From 5/91 to 6/93, 290 transabdominal preperitoneal (TAPP) laparoscopic herniorrhaphies were performed on 244 adult patients at Georgia Baptist Medical Center. Procedures consisted of indirect (164), direct (73), femoral (5), obturator (7), and recurrent (41) hernia repairs, with a mean operative time of 81.2 minutes (range 30-193 min). The overall technical complication rate was 5.3% and includes lateral thigh paresthesias (6), inferior epigastric artery injury (4), enterotomy during adhesiolysis (1), bowel obstruction secondary to herniation through a lateral trocar site (1), and bladder injury (1). The recurrence rate is 1% (3/290), with a mean follow up of 11 months (range 2-27 months). The authors present herein a discussion of technical considerations in an attempt to help decrease complications and recurrence as others incorporate laparoscopic hernia repair into their surgical armamentarium.

Esophageal perforation and acquired tracheoesophageal fistulae (ATEF) are rare sequelae of foreign body ingestion in the pediatric population. Here we discuss the cases of two patients with esophageal perforation caused by prolonged impaction of a coin; in one case, a tracheoesophageal fistula developed. The presence of aerodigestive symptoms and signs in infants and small children should prompt physicians to consider foreign body ingestion and the presence of an ATEF. Clinical presentation, diagnostic modalities, and technical considerations for surgical management are outlined.

Laparoscopic colon resections have often required an abdominal incision to remove the specimen and perform the anastomosis. Our aim was to mobilize the left colon and rectum using the laparoscope and perform a perineal proctosigmoidectomy with a primary end-to-end anastomosis. In eight pigs we used the operating laparoscope to mobilize the left colon, to ligate the inferior mesenteric artery at its origin, to ligate the inferior mesenteric vein as it crossed the left colic artery, and to fully mobilize the rectum. The rectum and sigmoid colon were then prolapsed through the anal canal, transected, and anastomosis was performed using an EEA stapler. The anastomosis was tested for structural and vascular integrity. Following the procedure, laparotomy was performed to estimate blood loss, to record visceral injury, and to examine the specimen for extent of resection. We were able to perform the resection and anastomosis in all animals with minimal blood loss and with high ligation of the vascular pedicle. There were no major visceral injuries. All anastomoses were perfused, patent, and intact. We concluded that when using the laparoscope in the porcine model, a low anterior resection and anastomosis can be performed safely with an adequate specimen without a laparotomy incision.
