Near total head resection of pancreas in patients with chronic pancreatitis - Outcome of a novel surgical technique.

BACKGROUND: Chronic pancreatitis (CP) is characterized by debilitating pain which affects patients' quality of life. Early surgical intervention has been shown to mitigate pain and prevent a decline in quality of life. The present study evaluated the impact of bile duct and duodenum preserving pancreatic head resection (BDPPHR), an innovative technique, on pain relief, functional outcomes, postoperative morbidity, and mortality in patients with CP. METHODS: Between March 2019 and July 2022, a total of 37 patients underwent bile duct and duodenum preserving pancreatic head resection (BDPPHR) for pain relief in patients with CP. Post-operative outcomes were assessed by Izbicki pain score, exocrine insufficiency, endocrine insufficiency, and return to work. The safety of the surgical procedure was determined by evaluation of postoperative morbidity and mortality as per Clavien-Dindo scores. RESULTS: BDPPHR showed a significant reduction in Izbicki pain scores with 30 (81 %) patients experiencing complete or partial pain relief up to 18 months of follow up. 32(86 %) patients ceased narcotic use by the end of the 18-month follow-up period. 33 (89 %) patients were able to resume regular work at the end of 18 months. There were no significant alterations in both exocrine and endocrine statuses post-surgery. The median duration of hospital stay was 4.5 days (3-11). Major complications occurred in 2 (5 %) patients. There was no post-operative mortality. CONCLUSION: BDPPHR is a novel and safe technique of near total head resection which results in very good pain relief in 81 % of patients.

A case of unusual evisceration through laparoscopic port site.

Drain site eviscerations have been reported as a rare complication following abdominal surgery. An 82-year-old women was diagnosed with carcinoma stomach and underwent laparoscopic subtotal gastrectomy. A few hours following removal of the duodenal stump drain, she developed small bowel evisceration through the drain site. It was successfully managed with immediate bedside release of fascial constriction followed by definitive repair later. Although herniations and eviscerations via larger drain sites have been reported, eviscerations from small laparoscopic port sites used for drains are rare. Here, we report the first case of small bowel evisceration with strangulation through a 5-mm port site.

Minimally invasive oesophagectomy in prone versus lateral decubitus position: A comparative study.

BACKGROUND: Thoracoscopic oesophageal mobilisation during a minimally invasive oesophagectomy (MIE) is most commonly performed with the patient placed in the lateral decubitus position (LDP). The prone position (PP) for thoracoscopic oesophageal mobilisation has been proposed as an alternative. MATERIALS AND METHODS: This was a retrospective, comparative study designed to compare early outcomes following a minimally invasive thoracolaparoscopic oesophagectomy for oesophageal cancer in LDP and in PP. RESULTS: During the study period, between January 2011 and February 2014, 104 patients underwent an oesophagectomy for cancer. Of these, 42 were open procedures (transhiatal and transthoracic oesophagectomy) and 62 were minimally invasive. The study group included patients who underwent thoracolaparoscopic oesophagectomy in LDP (n = 23) and in PP (n = 25). The median age of the study population was 55 (24-71) years, and there were 25 males. Twenty-one (21) patients had tumours in the middle third of the oesophagus, 24 in the lower third, and 3 arising from the gastro-oesophageal junction. The most common histology was squamous cell cancer (85.4%). The median duration of surgery was similar in the two groups; however, the estimated median intraoperative blood loss was less in the PP group [200 (50-400) mL vs 300 (100-600) mL; P = 0.01)]. In the post-operative period, 26.1% patients in the LDP group and 8% in the PP group (8%) developed respiratory complications. The incidence of other post-operative complications, including cervical oesophagogastric anastomosis, hoarseness of voice and chylothorax, was not different in the two groups. The T stage of the tumour was similar in the two groups, with the majority (37) having T3 disease. A mean of 8 lymph nodes (range 2-33) were retrieved in the LDP group, and 17.5 (range 5-41) lymph nodes were retrieved in the PP group (P = 0.0004). The number of patients with node-positive disease was also higher in the PP group (19 vs 10, P = 0.037). CONCLUSION: MIE in the PP is an effective alternative to LDP. The exposure obtained is excellent even without the need for a complete lung collapse, thereby obviating the need for a double-lumen endotracheal tube. A more meticulous dissection can be performed resulting in a higher lymph nodal yield.

Does elective re-siting of intravenous cannulae decrease peripheral thrombophlebitis? A randomized controlled study.

BACKGROUND: Peripheral venous thrombophlebitis (PVT) is a common complication of intravenous cannulation, occurring in about 30% of patients. We evaluated the effect of elective re-siting of intravenous cannulae every 48 hours on the incidence and severity of PVT in patients receiving intravenous fluids/drugs. METHODS: We randomized 42 patients who were admitted for major abdominal surgery to either the control or study group (n = 21 in either group). Informed consent was obtained from all of them. Cannulae in the control group were removed only if the site became painful, the cannula got dislodged or there were signs and symptoms suggestive of PVT, namely pain, erythema, swelling, excessive warmth or a palpable venous cord. Cannulae in the study group were changed and re-sited electively every 48 hours. All the patients were examined every 24 hours for signs and symptoms of PVT at the current and previous sites of infusion. RESULTS: The incidence of PVT was 100% (21/21) in the control group and only 9.5% (2/21) in the study group (p < 0.0001). The severity of PVT was also less in the study group compared with that in the control group. Day-wise correlation of the incidence of PVT showed that 82.6% of the episodes of PVT occurred on day 3. CONCLUSION: Elective re-siting of intravenous cannulae every 48 hours results in a significant reduction in the incidence and severity of PVT. We recommend that this should be adopted as standard practice in managing all patients who require prolonged intravenous therapy.

Estrogen and progesterone receptors in esophageal carcinoma.

Information is sparse and contradictory in the literature regarding the role of estrogen receptor (ER) and progesterone receptor (PR) in esophageal carcinoma. This study was conducted over a period of 18 months from September 2004 with the primary aim of determining the PR, ER alpha (ERalpha) and ER beta (ERbeta) status of esophageal carcinoma and normal esophageal mucosa (NEM). The receptor status was correlated with tumor type, tumor differentiation and tumor stage. A total of 45 patients with histologically proven squamous cell carcinoma (SCC) (n = 30) and adenocarcinoma (AC) (n = 15) were studied. Receptor status was detected by immunohistochemistry (IHC) and semiquantitative assessment was done by quick score method of endoscopic biopsy specimens. The mean age for SCC and AC were not significantly different. The gender ratio in favor of males was 3 : 2 for SCC and 4 : 1 for AC. None of the specimens from SCC or AC showed positivity for PR both in NEM and tumor tissue. Likewise none of the specimens were positive for ERalpha by IHC. The mean ERbeta score for AC was significantly higher than SCC. For SCC it was seen that ERbeta positivity in tumor cells increases with dedifferentiation and increasing tumor stage. This trend was seen for AC as well. ERbeta is over-expressed in poorly differentiated SCC and AC compared to NEM. Thus ERbeta may be a marker for poor biological behavior, that is dedifferentiation or higher stage of disease. In view of these findings we propose a large-scale prospective, longitudinal interventional study using selective estrogen modulators.
