Laparoscopic Roux-en-Y gastric bypass: Outcomes of a case-matched comparison of primary versus revisional surgery.

INTRODUCTION: Laparoscopic adjustable gastric banding and laparoscopic sleeve gastrectomy are popular bariatric procedures. Certain complications may necessitate revision. Adverse outcomes are reported after revisional bariatric surgery. We compared patients undergoing revisional versus primary laparoscopic Roux-en-Y gastric bypass (LRYGB). MATERIALS AND METHODS: This was retrospective comparative 1:1 case-matched analysis of revisional LRYGB Group A versus primary LRYGB (pLRYGB/Group B). Matching was based on body mass index (BMI) and comorbidities. BMI decrease at 6 and 12 months post-surgery, comorbidity resolution, operative time, morbidity and length of hospital stay (LOS) were compared. Total decrease in BMI, i.e., change from before initial bariatric procedure to 12 months after revision for Group A was also compared. RESULTS: Median BMI (inter-quartile range) for Group A decreased to 44.74 (7.09) and 41.49 (6.26) at 6 and 12 months, respectively, for Group B corresponding figures were 38.74 (6.9) and 33.79 (6.64) (P = 0.001 and P = 0.0001, respectively). Total decrease in BMI (Group A) was 9.8, whereas BMI decrease at 12 months for Group B was 15.2 (P = 0.23). Hypertension resolved in 63% (Group A), 70% (Group B) (P = 0.6). Diabetes resolution was 80% (Group A), 63% (Group B) (P = 0.8). Operative time for Groups A, B was 151 ± 17, 137 ± 11 min, respectively (P = 0.004). There was no difference in morbidity and LOS. CONCLUSION: Comorbidity resolution after revisional and pLRYGB are similar. Less weight loss is achieved after revision than after pLRYGB, but total weight loss is comparable. Revisional surgery is safe when performed by experienced surgeons in high-volume centres.

Laparoscopic management of infected mesh after laparoscopic inguinal hernia repair.

PURPOSE: We present our experience with 10 patients with infected meshes after laparoscopic inguinal hernia repair in whom we explanted infected meshes laparoscopically. METHODS: On retrospective analysis over 5 years (2007 to 2012), we identified 10 patients (6 TAPP/4 TEP) with localized deep-seated mesh infections in whom infected meshes were explanted laparoscopically. Peritoneum was incised, associated abscesses were drained, meshes were identified, separated, and extracted through 10/12 mm port. RESULTS: Nine patients experienced resolution of symptoms after 3 weeks of surgical intervention and remained asymptomatic at mean follow-up of 20 months (range, 4 to 42 mo). One patient with recurrent abscess required surgical drainage twice. Mean hospital stay was 2.2 days (range, 1 to 9 d). Two patients developed recurrent hernia at 6 and 8 months after mesh explantation. CONCLUSIONS: Laparoscopic explantation of infected meshes after laparoscopic hernia repair leads to less scarring and early recovery. Contamination of anterior abdominal wall after cutaneous drainage of deep-seated abscess is avoided.

Stump appendicitis: A rare clinical entity.

Stump appendicitis is one of the rare delayed complications after appendectomy with reported incidence of 1 in 50,000 cases. Stump appendicitis can present as a diagnostic dilemma if the treating clinician is unfamiliar with this rare clinical entity. We report an 18-year-old patient with Stump appendicitis, who underwent completion appendectomy laparoscopically.

Laparoscopic repair of suprapubic hernias: transabdominal partial extraperitoneal (TAPE) technique.

BACKGROUND: Suprapubic hernias are considered difficult to repair laparoscopically due to deficient posterior rectus sheath and proximity to important neurovascular structures and the urinary bladder. METHODS: 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. RESULTS: 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% CONCLUSION: 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.

Laparoscopic cholecystostomy is a safe and effective alternative in critically ill patients with acute cholecystitis: two cases.

Emergency cholecystectomy for acute cholecystitis in critically ill patients with organ failure and sepsis carries a high risk of morbidity and mortality. Temporizing interventions such as laparoscopic cholecystostomy can help the patient to recover from the critical illness by deferring the definitive procedure to a later, safer period. We describe our experience of laparoscopic cholecystostomy performed in two critically ill patients. In the first case, a 56-year-old man with hypertension, diabetes, and ischemic heart disease, was admitted for evaluation of malena. During the course of his stay, he developed acute calculous cholecystitis, acute renal failure, and right pleural effusion. In the second case, a 68-year-old man presented with diabetes, hypertension, diabetic nephropathy, acute chronic renal failure, and acute calculous cholecystitis. Both patients failed to improve with conservative measures and underwent laparoscopic cholecystostomy under local anesthesia and sedation in view of severe comorbidities and sepsis. Both patients recovered from sepsis. Laparoscopic cholecystectomy was performed uneventfully after six and eight weeks, respectively, and both patients were doing well at one-year follow-up.

Laparoscopic management of cholecystoenteric fistulas.

BACKGROUND: Cholecystoenteric fistulas are a rare complication of gallstone disease and affect 3-5% of patients with cholelithiasis. Most fistulas are diagnosed intraoperatively. MATERIALS AND METHODS: Between January 1997 and June 2003, 12428 patients underwent laparoscopic cholecystectomy at our department. Cholecystoenteric fistula was diagnosed intraoperatively and treated in 63 patients: 45 patients (71.4%) had cholecystoduodenal fistulas, while cholecystogastric and cholecystocolic fistulas were found in 9 patients (14.3%) and 4 patients (6.3%), respectively; and 5 patients (7.9%) were found to have Mirizzi syndrome type I along with a cholecytoenteric fistula. The operation could be completed laparoscopically in 59 patients. An endostapler was used in 47 patients to transect the fistula and in 12 patients the defect in the bowel was repaired with intracorporeal sutures. RESULTS: Major morbidity occurred in 3 patients (4.76%). One patient developed a loculated subdiaphragmatic collection which was treated by ultrasound guided aspiration and antibiotic therapy. Prolonged biliary drainage occurred in 2 patients. In addition, 7 patients (11.11%) had minor postoperative complications. The mean postoperative hospital stay was 5.2 days. All the patients are asymptomatic at a mean follow-up of 2.4 years. CONCLUSION: Cholecystoenteric fistula is a difficult problem usually diagnosed intraoperatively. A high degree of suspicion at operation is mandatory. A stapled cholecystofistulectomy may be the procedure of choice since it avoids contamination of the peritoneal cavity. Complete laparoscopic management of cholecystoenteric fistulas is possible in well-equipped high-volume centers.

A rare psoas hernia: endoscopic diagnosis and management.

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.

Mesh migration into the bladder after TEP repair: a rare case report.

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.

Laparoscopic approach to pheochromocytoma: is a lower intraabdominal pressure helpful?

Laparoscopic adrenalectomy is gaining popularity because of its well-documented benefits. The aim of our study was to see if a decreased intraoperative intraabdominal pressure during laparoscopic adrenalectomy would affect the hemodynamic variables and the serum levels of catecholamines. We randomly divided 9 patients into 2 groups, maintaining either an intraabdominal pressure of 15 mm Hg (group A) or 8-10 mm Hg (group B). Norepinephrine and epinephrine blood levels were measured preoperatively, during endotracheal intubation, carboperitoneum, surgical manipulation of tumor just before the ligation of the adrenal vein, and tracheal extubation; the hemodynamic variables were recorded. The introduction of carboperitoneum resulted in an increase in heart rate and mean arterial blood pressure (MAP), although it was statistically insignificant. The norepinephrine levels showed a statistically significant increase in group A as compared with group B (P = 0.0002). Surgical manipulation of the tumor resulted in a significant increase in MAP and norepinephrine levels in group A (P = 0.007 and P = 0.0001, respectively). The epinephrine levels did not change as much because the tumor was probably predominantly norepinephrine-secreting. Norepinephrine levels continued to be high even during tracheal extubation in group A patients (P = 0.027). We conclude that a low intraabdominal pressure of 8-10 mm Hg causes less catecholamine release and fewer hemodynamic fluctuations.

Elective laparoscopy in diagnosis and treatment of recurrent small bowel obstruction.

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.

Abdominal wall sinus: an unusual presentation of spilled gallstone.

Gallbladder perforation and spillage of bile is common during laparoscopic cholecystectomy. We report a case of an abdominal wall sinus due to a spilled gallstone presenting 10 years after laparoscopic cholecystectomy.

Sir Ganga Ram Hospital classification of groin and ventral abdominal wall hernias.

BACKGROUND: Numerous classifications for groin and ventral hernias have been proposed over the past five to six decades. The old, simple classification of groin hernia in to direct, inguinal and femoral components is no longer adequate to understand the complex pathophysiology and management of these hernias. The most commonly followed classification for ventral hernias divide them into congenital, acquired, incisional and traumatic, which also does not convey any information regarding the predicted level of difficulty. AIM: All the previous classification systems were based on open hernia repairs and have their own fallacies particularly for uncommon hernias that cannot be classified in these systems. With the advent of laparoscopic/ endoscopic approach, surgical access to the hernia as well as the functional anatomy viewed by the surgeon changed. This change in the surgical approach and functional anatomy opened the doors for newer classifications. The authors have thus proposed a classification system based on the expected level of intraoperative difficulty for endoscopic hernia repair. CLASSIFICATION: In the proposed classification higher grades signify increasing levels of expected intraoperative difficulty. This functional classification grades groin hernias according to the: a) Pre -operative predictive level of difficulty of endoscopic surgery, and b) Intraoperative factors that lead to a difficult repair. Pre operative factors include multiple or pantaloon hernias, recurrent hernias, irreducible and incarcerated hernias. Intraoperative factors include reducibility at operation, degree of descent of the hernial sac and previous hernia repairs. Hernial defects greater than 7 cm in diameter are categorized one grade higher. CONCLUSION: Though there have been several classification systems for groin or inguinal hernias, none have been described for total classification of all ventral hernias of the abdomen. The system proposed by us includes all abdominal wall hernias and is a final classification that predicts the expected level of difficulty for an endoscopic hernia repair.

Totally extraperitoneal repair of inguinal hernia: Sir Ganga Ram Hospital technique.

Laparoscopic approach for hernia has evolved rapidly over the past decade. We adopted the TEP repair early as we believe in preserving the sanctity of the coelomic cavity. Once well versed with the approach we have found it an efficient and cost effective method for groin hernia repair.Endoscopic totally extraperitoneal hernia repair is a technically demanding procedure. Indepth anatomical knowledge, training and advanced technical skill is needed for the surgeon to perform this procedure. To make the procedure cost effective and prevent hernia recurrences, we have modified and innovated to simplify the procedure.This modification which we have named the SGRH technique, innovates by creating the preperitoneal working space with the help of an indigenous glove finger balloon. A rolled mesh makes placement and fixation easier in the limited working space. The mesh is unrolled on the peritoneal surface (floor), a manouver which is technically simpler. On desufflation the mesh comes to appose the Fruchad's orifice covering all potential hernial sites. With the modified SGRH technique we have found TEP to be safe, cost effective, reproducible and without significant complications.

Totally extraperitoneal repair of inguinal hernia: A case for bilateral repair.

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.

Complications in groin hernia surgery and the way out.

Complications in endoscopic inguinal hernia surgery are more dangerous and more frequent than those of open surgery, especially in inexperienced hands and hence are best avoided. It is possible to avoid most of these complications if one follows a set of well-defined steps and principles of endoscopic inguinal hernia surgery.Complications are known to occur at each and every step of hernia surgery. Applying caution while performing each step can save the patient from a lot of morbidity. One starts by applying strict patient selection criteria for endoscopic hernia repair, especially in the initial part of ones learning curve. A thorough knowledge of anatomy goes a long way in avoiding most of the complications seen in hernia repair. This anatomy needs to be relearned from what one is used to, as the approach is totally different from an open hernia repair. And finally, learning and mastering the right technique is an essential prerequisite before one ventures into inguinal hernia repair.Although there has been an increased incidence of complications reported in endoscopic repair in the earlier series, this can be explained partly by the fact that it was in the early part of the learning curve of most endoscopic surgeons. As the experience grew and the techniques were standardized, the incidences of complications have also reduced and have come to be on par with open hernia surgery. The various complications and precautions to be taken to avoid them will be discussed.

Laparoscopic repair of ventral / incisional hernias.

Despite its significant prevalence, there is little in the way of evidence-based guidelines regarding the timing and method of repair of incisional hernias. To add to the above is the formidable rate of recurrence that has been seen with conventional tissue repairs of these hernias. With introduction of different prosthetic materials and laparoscopic technique, it was hoped that an improvement in the recurrence and complication rates would be realized. The increasing application of the laparoscopic technique across the world indicates that these goals might indeed be achieved.

Laparoscopic cholecystectomy in a patient with ankylosing spondylitis with severe spinal deformity.

Laparoscopic cholecystectomy is the current gold standard for the management of cholelithiasis. As experience with laparoscopic cholecystectomy has increased, contraindications to the procedure have started decreasing. Kyphoscoliosis with fixed rigidity is considered as a relative contraindication to laparoscopic surgery. Ankylosing spondylitis is a challenge to the anaesthesiologist because it is associated with difficult intubation, restrictive ventilatory defects, and frequent cardiac involvement. The benefits of laparoscopic surgery can be extended to this group of patients with severe kyphoscoliosis due to advances in anesthesia and surgical expertise. We report a case of laparoscopic cholecystectomy performed in a patient with severe ankylosing spondylitis with fixed rigidity of the cervical spine and marked thoracolumbar kyphosis with severe restrictive lung disease. The purpose of this report is to describe the difficulties encountered in anesthesia and operative difficulties due to altered body habitus in terms of patient positioning and surgical access.

Laparoscopic repair of diaphragmatic hernias: experience of six cases.

OBJECTIVE: Laparoscopic diaphragmatic hernia repair is increasingly performed in adults for congenital diaphragmatic hernias and chronic traumatic diaphragmatic hernias. This study reviewed our experience with laparoscopic diaphragmatic hernia repair to evaluate its safety, efficacy and outcomes. METHODS: Between January 1999 and December 2002, four male and two female patients presented to us with diaphragmatic hernias, three with traumatic and three with congenital hernias. The mean age of patients was 58.6 years (range, 42-83 years). Five patients presented with main complaints of postprandial retrosternal/chest discomfort and one patient had an acute gastric outlet obstruction. Dissection was performed laparoscopically to reduce the contents of the sac and the hernial defect was repaired using prolene sutures and a polypropylene mesh. RESULTS: Laparoscopic repair of diaphragmatic hernias was completed successfully in all patients. The mean size of the defect was 6.8 cm (range, 3-12 cm) and the mean operative time was 100 minutes (range, 60-150 minutes). There were no major intraoperative complications. One patient required placement of a chest tube due to inadvertent opening of the pleura with the hernial sac and one patient had prolonged postoperative gastric ileus. The mean hospital stay was 2.3 days (range, 1-4 days) and the mean pain score was 4 (range, 2-6). All patients remained asymptomatic over a mean follow-up of 2.9 years. CONCLUSION: Adult congenital and chronic traumatic diaphragmatic hernias are amenable to laparoscopic repair. Laparoscopic repair is safe and feasible and confers all the advantages of minimal access surgery.

Laparoscopic splenectomy for hematologic disorders: experience with the first fifty patients.

BACKGROUND: Splenectomy is increasingly being performed by various minimal access surgical modalities for select hematologic disorders. METHODS: 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%). RESULTS: 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). CONCLUSION: 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.

Endoscopic management of a retroperitoneal hydatid cyst.

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.
