Article: Concomitant laparoscopic ventral hernia mesh repair and bariatric surgery: a retrospective study from a tertiary care center.
[show abstract] [hide abstract]
ABSTRACT: To analyze the safety in combing laparoscopic ventral hernia repair with a mesh and bariatric surgery. Obesity is one of the important precipitating factors for primary and recurrent ventral hernias (incisional and umbilical) and it is not uncommon to find these hernias in patients opting for obesity surgery. But, with no consensus or recommendation and concern of mesh infection, surgeons fear in combining these procedures, especially Roux en Y gastric bypass and sleeve gastrectomy. In this study, we have retrospectively analyzed all patients who underwent concomitant bariatric procedure and mesh repair for ventral hernia at our institute. A total of 36 out of 765 patients operated at our institute between 2003 and 2011 had concomitant procedures. Eleven patients had Roux en Y gastric bypass (group I) and remaining 25 had sleeve gastrectomy (group II) performed on them. The operating times were 149 min(120-210 min) in group I and 122 min (90-220min) in group II. No immediate complications or any incidence of mesh infection or recurrence in either of the groups. Concomitant mesh repair for ventral hernias can be safely combined with bariatric procedures like Roux en Y gastric bypass and sleeve gastrectomy. But, for beginners, these should be done only in selected cases after fully informed consent from the patients.Obesity Surgery 02/2012; 22(5):685-9. · 3.29 Impact Factor -
Article: Minimally invasive oesophagectomy for carcinoma oesophagus--approaches and options in a high volume tertiary centre.
[show abstract] [hide abstract]
ABSTRACT: Minimally invasive oesophagectomy is being increasingly performed for treatment of carcinoma oesophagus. In this article, we overview the different types of minimally invasive oesophagectomies we used in our experience. To present an overview of the different types of minimally invasive oesophagectomies used to treat carcinoma oesophagus and to propose a simple working algorithm for surgical management of carcinoma oesophagus, a retrospective review of patients with carcinoma oesophagus who were operated at this centre during the period 1997-2009 was made. Data regarding type of surgery, level of growth, type of carcinoma, and complications were reviewed. A total of 463 patients underwent minimally invasive oesophagectomy for carcinoma oesophagus. Of these, 121 patients (26%) were female. There were no conversions. The mean age of patients was 61.6 years (range 36 years-77 years). Most patients (n = 330; 71%) had squamous cell carcinoma while 133 patients (29%) had adenocarcinoma. Overall mortality was 0.9%. Overall morbidity was 16%. Minimally invasive approaches to oesophagectomy are safe and the type of approach has to be tailored for the histology, level and stage of growth.Journal of the Indian Medical Association 10/2010; 108(10):642-4. -
Article: Transumbilical flexible endoscopic cholecystectomy in humans: first feasibility study using a hybrid technique.
[show abstract] [hide abstract]
ABSTRACT: Natural-orifice transluminal endoscopic surgery (NOTES) procedures have been tested using numerous approaches, mainly in animals. In humans, only cholecystectomy has been assessed, using a combined transvaginal and transumbilical approach. We present another variant of a hybrid technique for cholecystectomy, namely the combination of a flexible transumbilical double-channel endoscope and a 3-mm rigid transcutaneous trocar placed in the left hypochondrium for liver retraction. The procedure was attempted in 10 well-selected young patients (M : F = 4 : 6, mean age 29.5 years). Instruments used through the two working channels of the endoscope were either a grasping forceps or snare for grasping and pulling and a hot-biopsy forceps for cold and hot preparation and dissection. Endoclips were used for cystic duct and artery closure. Postoperative analgesia consisted of one intravenous dose of analgesic, followed by oral administration for one further day. Follow-up visits were scheduled at 7 days, 30 days, 90 days, and 6 months. In 4 of the 10 cases the operation had to be converted to conventional laparoscopic cholecystectomy due to difficulty in dissection (in 2 cases) or uncontrollable hemorrhage (2 cases). The mean operating time was 148 minutes. Of the 6 cases in which the procedure was finished by the new approach, cystic artery bleeding occurred in 1 and was successfully clipped. One further patient had a postoperative cystic duct leak with a bilioma, successfully treated by endoscopic retrograde cholangiopancreatography with stenting. Five of the six patients reported themselves as satisfied at 3- or 6-month follow-up. So far, our endoscope-based transumbilical cholecystectomy technique has not yielded satisfactory results in humans. Further instrument and accessory improvements may increase both success rate and acceptance. Scarless surgery without the inherent risks of a transluminal approach may then become feasible.Endoscopy 06/2008; 40(5):428-31. · 5.21 Impact Factor -
Article: Laparoscopic anterior resection and total mesorectal excision for rectal cancer: a prospective nonrandomized study.
[show abstract] [hide abstract]
ABSTRACT: The purpose of this study was to present our experience of laparoscopic total mesorectal resection, including ultralow resection and coloanal anastomosis. Between 1993 and 2005, patients fit for general anesthesia, with resectable cancers, and with lower edge of tumor beyond 5 cm of the anal verge were subjected to laparoscopic anterior resection with sphincter preservation. Double stapling technique is used to establish bowel continuity. A total of 170 patients, 88 males and 82 females, were subjected to successful laparoscopic anterior resection, which included high anterior resection (n=90), low anterior resection (n=52), ultralow anterior resection (n=20), and coloanal anastomosis (n=8). The average age of patients was 58.4 years (12-90 years). Mean operating time was 130 min and mean hospital stay was 7 days. The morbidity was 13.5% with nil mortality. With an average follow-up of 49 months (range 9 years to 3 months), 9 patients developed local recurrence and 45 patients developed distant metastasis. In selected cases, laparoscopic anterior resection is possible for all levels of rectal tumors, allowing sphincter preservation and maintaining oncological safety.International Journal of Colorectal Disease 05/2007; 22(4):367-72. · 2.38 Impact Factor -
Article: Laparoscopic distal pancreatectomy: results of a prospective non-randomized study from a tertiary center.
[show abstract] [hide abstract]
ABSTRACT: Though laparoscopic distal pancreatectomy for benign conditions was first described in the early 1990s, it has not become as popular as other laparoscopic surgeries. Published literature on this topic consists of several case reports and a handful of small series. We present our experience, which, to the best of our knowledge, is the largest series reported to date. Since 1998, 22 patients have undergone distal pancreatectomy at our institute. The technique of distal pancreatosplenectomy, as well as spleen-preserving distal pancreatectomy, is described. Four males and 18 females in the age range of 12-69 years underwent operation. Splenic preservation was possible in 7 patients. The tumor diameter ranged from 2.1 cm to 7.4 cm. The mean operating time was 215 min. The mean length of incision required for specimen retrieval was 3.4 cm. All patients were started on a liquid diet on the first postoperative day. The median hospital stay was 4 days. One patient developed a pancreatic fistula that was managed conservatively. At the end of an average follow-up of 4.6 years, no recurrence has been reported. Laparoscopic distal pancreatectomy is a safe procedure, with minimal morbidity, rapid recovery, and short hospital stay. In appropriate cases, splenic preservation is feasible.Surgical Endoscopy 04/2007; 21(3):373-7. · 4.01 Impact Factor -

Article: Palanivelu hydatid system for safe and efficacious laparoscopic management of hepatic hydatid disease.
[show abstract] [hide abstract]
ABSTRACT: Hydatid disease, being endemic in several areas of the world, is of interest even to surgeons in non-endemic areas because they may encounter the disease due to ease and rapidity of travel as well as immigration. We describe a new device for laparoscopic management of hepatic hydatid disease. The special trocar-cannula system--the Palanivelu hydatid system (PHS)--and the technique of operation are described. A total of 75 patients were operated on using this technique. In 83.3% of patients, only evacuation of the hydatid cyst by the PHS was done. In 13.7%, this was followed by left lobectomy because the cysts were large, occupying almost the entire left lobe of the liver. The remnant cavity was dealt with by omentoplasty. The average follow-up period was 5.9 years, during which there were no recurrences. PHS is successful in preventing spillage, evacuating the contents of hydatid cysts, performing transcystic fenestration, and for dealing with cyst-biliary communications.Surgical Endoscopy 01/2007; 20(12):1909-13. · 4.01 Impact Factor -

Article: Laparoscopic lateral pancreaticojejunostomy: a new remedy for an old ailment.
[show abstract] [hide abstract]
ABSTRACT: Lateral pancreaticojejunostomy is considered as the standard surgery for chronic pancreatitis. Yet there are very few reports of this procedure being done laparoscopically. We present our experience with laparoscopic lateral pancreaticojejunostomy till date and describe our technique. Since 1997, we have done 12 laparoscopic lateral pancreatojejunostomies. There were 9 females and 3 males and the average age was 29.3 years. The indication for surgery in all patients was intractable abdominal pain and significant weight loss. Additionally, two patients were also suffering from pancreatic ascites. The average diameter of the pancreatic duct was 14.7 mm. We used a four-port technique. All surgeries were completed without any conversion to open surgery. Post-operatively, there were no major morbidity and nil mortality. The average operating time was 172 minutes. Post-operative stay was short (average 5 days) and on median follow-up of 4.4 years, 83.3% patients had complete pain relief while 16.7% had partial relief. All patients had significant weight gain. Laparoscopic lateral pancreaticojejunostomy is safe, effective and feasible in experience hands. Mastery of intracorporeal knotting and suturing techniques is mandatory before embarking on this surgery.Surgical Endoscopy 04/2006; 20(3):458-61. · 4.01 Impact Factor -

Article: Laparoscopic management of hepatic hydatid disease.
[show abstract] [hide abstract]
ABSTRACT: Hydatid disease is an endemic condition in several parts of the world. Owing to ease of travel, even surgeons in nonendemic areas encounter the disease and should be aware of its optimum treatment. A safe, new method of laparoscopic management of hepatic hydatid disease is described along with a review of the relevant literature. Sixty-six cases of hepatic hydatid disease were operated on laparoscopically using the Palanivelu Hydatid System. The special trocar-cannula system used and the technique of operation are described. The majority of the patients presented with pain. Most of the patients had only a single cyst. The right lobe of the liver was most commonly involved. Cysts were bilateral in 4 patients. In 83.3%, simply evacuation of the hydatid cyst by the Palanivelu Hydatid System was done. In 13.7%, this was followed by a left lobectomy, as the cysts were large occupying almost the entire left lobe of the liver. The remnant cavity was dealt with by omentoplasty. The average follow-up period is 5.8 years. There have been no recurrences to date. We recommend Palanivelu Hydatid System for management of hepatic hydatid disease. We have found its efficacy to be optimum for preventing spillage, evacuating hydatid cyst contents, performing transcystic fenestration, and for dealing with cyst-biliary communications.JSLS: Journal of the Society of Laparoendoscopic Surgeons / Society of Laparoendoscopic Surgeons 10(1):56-62. · 0.98 Impact Factor
