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 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.

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.

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.

Endoscopic totally extraperitoneal repair for occult bilateral obturator hernias and multiple groin hernias.

INTRODUCTION: 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. METHODS: 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. RESULTS: The patient was discharged the next day and is symptom-free on followup at eight months. CONCLUSION: 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.

Abandoned endoscopic procedures.

Intraoperatively, it may be prudent at times to abandon or defer the intended therapeutic procedure due to adverse prevailing conditions. A decision to abandon or defer an endoscopic procedure would necessarily result in less morbidity compared with conventional open surgery. A retrospective review of endoscopic procedures that were abandoned or deferred and subsequent patient outcomes were noted. Between January 1998 to May 2003, 48 procedures out of a total of 11,550 endoscopic surgical procedures had to be abandoned. Previously unsuspected intraabdominal malignancy was the cause in 32 patients. Anesthesia-related problems led to the decision in 6 patients. Coincidental tuberculosis and failure in accessing the target organ were the cause in two patients each. An ectopic gallbladder, an absent gallbladder, a pancreatic phlegmon, and a failure to achieve proper single-lung ventilation led to the decision in one patient each. In two patients, presence of dense intraabdominal adhesions that precluded further progress led the surgeon to abandon the surgery. The patients with intraabdominal malignancy were staged for their disease and treated accordingly. Nine patients without malignancy who had their operation deferred due to diverse reasons were operated on a later date, whereas 4 patients were lost to follow-up. The 9 patients who underwent operation at a later date are well on follow-up. Four patients with intraabdominal malignancy died, whereas the others are well in follow-up after being treated according to the stage of their disease. Certain adverse situation encountered intraoperatively may lead the surgeon to change the approach to surgery and abandon the procedure. He may consider operation at a suitable time later or consider a different treatment altogether. The morbidity consequent to such a decision is much less if the operative approach is an endoscopic one.

Ectopic gallbladder: laparoscopic cholecystectomy.

An unusual case of ectopic retroplaced gall bladder is reported. In our patient, this congenital anomaly was detected on ultrasonography and confirmed by CT scan, MRCP, and ERCP. Laparoscopic cholecystectomy was performed without complications. The importance of proper preoperative investigations is emphasized for accurate diagnosis, to rule out biliary tract anomalies, and to properly plan surgical approach and management.

Recurrent hernia following endoscopic total extraperitoneal repair.

BACKGROUND AND PURPOSE: 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. METHOD: 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. RESULTS: 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. CONCLUSION: 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.

Laparoscopic reintervention for residual gallstone disease.

Laparoscopic reintervention is being increasingly performed in patients who have previously undergone surgery for gallstone disease. A few patients with gallbladder remnants or a cystic duct stump with residual stones have recurrent symptoms of biliary disease. Patients with bile duct injuries were excluded from the study. We reviewed our experience in treating such patients over a 4-year period, January 1998 through December 2001. Five patients underwent laparoscopic reintervention after previous surgery for gallstone disease performed elsewhere during the period mentioned above. Of these 5 patients, 3 had impacted stones in gallbladder remnants (laparoscopic cholecystectomy, 2; open cholecystectomy, 1) and 2 had recurrent symptoms after cholecystolithotomy and tube cholecystostomy (conventional surgery) performed elsewhere. Laparoscopic excision of the gall bladder remnants was done in 3 patients and a formal laparoscopic cholecystectomy was done in 2 patients who had previously undergone cholecystolithotomy and tube cholecystostomy. The mean operating time was 42 minutes. No drainage was required postoperatively. All patients were symptom-free during a mean follow-up of 2.3 years (range, 7 months to 4 years). Reintervention may be required for patients with residual gallstones whose symptoms recur after gallbladder surgery such as cholecystectomy, subtotal cholecystectomy, and tube cholecystostomy. It is safe and feasible to remove the gallbladder or gallbladder remnants in such patients laparoscopically.

Laparoscopic ventral hernia repair with extraperitoneal mesh: surgical technique and early results.

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.

Combined procedures in laparoscopic surgery.

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.

Complete laparoscopic management of choledochal cyst: report of two cases.

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 5(th) 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.

Laparoscopic excision of a lower posterior mediastinal paraspinal mass: technique and feasibility of the laparoscopic approach.

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.
